  a. alkaline phosphatase level.
  b. acid phosphatase level.
  c. serum amylase level.
  d. uric acid level.

Question 2

The nurse is teaching cardiovascular risk factors to a group of older adults. The nurse stresses that cigarette smokers are four times more likely to die of sudden cardiac death than nonsmokers because smoking

Answer to Question 1

B
Acid phosphatase is an enzyme that is primarily located in the prostate gland. Acid phosphatase levels are used to diagnose prostate cancer and to estimate the extent of the disease. The other values are not related.

Answer to Question 2

D
Smoking increases platelet aggregation and causes coronary artery spasms. Nicotine increases blood pressure and cardiac demands. Carbon monoxide in tobacco smoke decreases the oxy-gen-carrying capacity of the blood. Smoking does not interfere with collateral circulation or produce strictures, but it may contribute to higher levels of carbon monoxide in the blood.
